Aggregate water-use establishment An Aggregate Water-Use Establishment represents an aggregate class of water-using establishments or individuals that are associated with a specific geographic location and water-use category, such as all the industrial users located within a county or all self-supplied domestic users in a county. An aggregate water-use establishment site type is used when specific information needed to create sites for the individual facilities or users is not available or when it is not desirable to store the site-specific information in the database.
